Is nanomedicine the next big thing? A growing number of top drug companies seem to think so.

The ability to encapsulate potent drugs in tiny particles measuring billionths of a meter in diameter is opening up new options for super-accurate drug delivery, increasing precision hits at the site of disease with, hopefully, fewer side effects.

Young athletes continue to play through concussion symptoms, study shows

Despite the widely known risks associated with concussions, many U.S. high-school football players said they wouldn’t report symptoms to a coach and would continue to play even if they had a headache resulting from an on-field injury, Medical Xpress reported via Fox News.
